Cohorts

Some of our Cohorts formed many years ago while others are just being added by new members. Cohorts are usually defined as “a group of people banded together” or “a group of people with a common characteristic.” You do not need to be a member to participate in our cohorts although we would greatly appreciate a membership contribution.  In JCo’s case, cohorts are individuals who have come together as Jews with common passions and talents and enjoy each others’ company.

Each cohort is a brainchild of our members.  We aim to connect individuals who share common interests and want to establish relationships with others. Cohort members create memories and experiences thereby creating a community that enjoys being Jewish together while being productive. 


If you would like to join or start a cohort please contact
